[LUPUS]

Here you see two different pistol slides and frames, the one without a firing pin block safety, the Steyr M9 is on the left, and the one with a firing pin block safety, Glock is on the right. Steyr M9 absolutely does not have any device to be thought as a firing pin block safety and its lever while the Glock has both.















Also there is nothing to be thought as a firing block safety in the slide assembly parts.







Here you can see the firing pin block and its spring in the Glock parts.
